But if you're one of the many who didn't manage to buy a ticket in the first two frenetic ticket releases last year, don't fret: this morning, thousands of new tickets will go on sale in the first proper extension of the play since it opened. Here's what you need to know

Do I need to book tickets for both parts?

If you want to see both parts, yes. The vast majority of people going do. The good news is that you keep the same seat for both sections, the bad news is that you may have to raid Gringotts to pay for them.

On Wednesdays, Saturdays and Sundays, both Part I and Part II are performed in one day. On Wednesdays and Saturdays, Part I takes place at 2pm, then Part II kicks off at 7.30pm. On Sunday, Part 1 begins at 1pm, while Part 2 starts at 6.30pm.

On Thursdays Part I is performed at 7.30pm, and on Fridays Part II is performed at 7.30pm. Most people try to see both parts in the same week. If you don't, there's a chance that the actors will change between performances due to holidays.

What if I miss out this time?

The good news is that throughout the run, including from now, there are tickets available every Friday as part of Harry Potter and the Cursed Child's Friday Forty scheme.

Every Friday at 1pm 40 tickets are released for every performance of the following week, in the best seats in the theatre.

Lucky customers are chosen at random to be given the opportunity to buy a maximum of two tickets for both Part One and Part Two in one transaction, for £40 total (£20 per part).

To be in with a chance, visit the Friday Forty page here at Friday lunchtime and hit the "book tickets" button at 1pm. You'll be entered into a virtual queue.

Will Harry Potter and the Cursed Child reach international theatres?

If the producers have decided to take the play to Broadway, they're keeping schtum. Producer Sonia Friedman told The New York Times that they are thinking about it, but haven't firmed down any details yet. "Of course, it would be disingenuous to think New York and Broadway weren’t part of our thinking," she told the paper.

“Harry Potter, the brand and the story, are as iconic over there as anywhere in the world, and, Colin and I being theater producers and Broadway producers, of course it’s on our radar, but where, how, when and with whom, we have no idea.”
